I think he was ok, penalty was bad but not as bad as you make it seem. He made a last second effort to block mctominays potential shot. Happens i guess
It might just a milisecond decision but tackle to the ground like that and in the penalty box increase the chance of the foul. With penalty, scoring opportunity is bigger. Its not the best decision to take at that moment. It also probably he also was tired, and thats the reason we lost the midfield and 2nd ball in 2nd half. Motta should have subs him or Koop earlier with Luiz / Fagioli to gain control back
